Bumbu Ketoprak is an Indonesian peanut dressing that comes in a dried brick.
Ingredients are: ground peanuts, onion, sugar, salt, spices, chili, garlic,
and soya sauce.
I found it available at: Kalustyans.
Cut off approximately 2 oz of the Bumbu and dissovle in 1/2 cup boiling water.

Chop garlic. Dice tomatoes briefly in a food processor.

De-bone and remove skin from chicken breasts.
Cut chicken into thin strips and brown in olive oil.
Throw in some chopped garlic.
